[0040] Reference Figure 1-2 The automatic material box conveying mechanism includes a frame 100 and a wall panel 101 mounted on the frame. The frame 100 is used to install other mechanisms of the automatic feeder. The wall panel 101 serves as the outer shell structure, providing overall support and fixation for the automatic feeder, isolating the internal mechanisms from the external environment, protecting the internal mechanisms, and preventing dust, etc. The frame 100 includes an upper frame 110, a middle frame 120, and a lower frame 130, arranged in upper, middle, and lower layers. Each frame includes an external frame A and a working space enclosed by the frame A. The following mechanisms are installed sequentially on the frames or bottom of the upper, middle, and lower frames according to their functions and processes. The material box 2 moves within the working space of each frame layer.

[0041] The automatic feeding machine includes a feeding mechanism 200, a lowering mechanism 800, and a discharging mechanism 900.

[0042] Reference Figure 1 and Figure 3The feeding mechanism 200 is located on the bottom edge of the middle frame 120, with its terminal being the pallet loading station B. The feeding mechanism 200 is used to transport the material box 2 to the loading station B. The upper frame 110 has a picking mechanism 700 located above and to the side of the loading station B. The picking mechanism 700 picks up the material and automatically loads it. Below and to the side of the picking mechanism 700 is a lowering mechanism 800, which is used to transport the material box 2 from the middle frame 120 to the lower frame 130. The lower frame 130 has a discharging mechanism 900 located below the feeding mechanism 200. The lowering mechanism 800 also has a material box conveying mechanism 810, which is used to transport the material box 2 to the discharging mechanism 900, from which it is removed from the automatic feeder. The aforementioned automatic feeding machine sequentially installs each mechanism on the frame or bottom of the upper, middle, and lower layers of the machine frame. The material bin 2 moves within the working space of each layer of the machine frame, resulting in a rational layout, space saving, and high work efficiency. Furthermore, the presence of frames or bottoms for each mechanism on the upper, middle, and lower layers facilitates maintenance and repair. In addition, the automatic feeding machine achieves automatic feeding, resulting in high work efficiency and cost savings. With the material-retrieving mechanism located on the upper layer of the machine frame, the worktable for placing the material can be positioned anywhere beside it after the material is retrieved, increasing the flexibility of worktable placement and making it suitable for various working environments.

[0043] Better, refer to Figure 1 The middle frame 120 is provided with a material box clamping component 140 on each side of the material box 2 in the conveying direction. The material box clamping component 140 is used to limit the opposite sides of the material box to prevent it from shifting, which would cause the pallet 1 to shift and affect the material picking.

[0044] Preferably, the middle rack 120 is also provided with a material box blocking component 150 in the material box conveying direction. The material box blocking component 150 limits the conveying distance of the material box 2 to prevent it from passing the pallet loading station B.

[0045] It should be understood that the feeding mechanism 200 can be a mechanical feeding mechanism, which drives the feeding components to move through a mechanical transmission device, such as gears, chains, belts, etc., to realize the material conveying; it can also be a pneumatic feeding mechanism, which uses the power generated by the piston compressing air to push the material to move; or it can be a hydraulic feeding mechanism, which is based on a hydraulic system and drives a hydraulic cylinder or hydraulic motor through the pressure of hydraulic oil to drive the feeding device to realize the material conveying.

[0046] As an embodiment of this utility model, refer to Figure 3The feeding mechanism 200 of this utility model is a belt-type feeding mechanism. Specifically, the feeding mechanism 200 includes two parallel first mounting seats 210, two first crossbeams 211 connecting the middle of the two first mounting seats 210, and a first drive rod 212 and a first driven rod 213 connecting the ends of the two first mounting seats 210. A first motor 220 is mounted on one of the first crossbeams 213. A first drive wheel 221 is provided on the motor shaft of the first motor 220, a first driven wheel 222 is fixed on the first drive rod 212, and a first belt 223 is tensioned and wound around the first drive wheel 221 and the first driven wheel 222. First rollers 214 are fixed at both ends of the first drive rod 212 and the first driven rod 213, and two first conveyor belts 215 are tensioned and wound around a pair of first rollers 214 on the same side of the first drive rod 212 and the first driven rod 213, respectively. The first motor 220 drives the first drive wheel 221 to rotate, which in turn drives the first driven wheel 213 to rotate via the first belt 223. This drives the first drive rod 212 and the first roller 214 on it to rotate, thereby driving the first conveyor belt 215 to move and moving the material box 2 placed on the first conveyor belt 215.

[0047] Preferably, the two first mounting bases 210 are respectively provided with a carrying plate 216 on the side near the first conveyor belt 215. The carrying plate 216 is located below the conveyor belt, so as to bear the weight of the material box 2 and prevent the first conveyor belt 215 from deforming under the weight and being unable to move smoothly.

[0048] The outer sides of the two first mounting bases 210 are respectively fixed with first mounting plates 217, and are fixedly connected to the middle rack 120 through the first mounting plates 217.

[0049] Better, refer to Figure 3 The feeding mechanism is equipped with a loading platform 230 for placing the material box 2. Specifically, the loading platform 230 is installed on the first mounting base 210, covering the first motor 220, the first driven rod 213 and the first crossbeam 211, thereby preventing the material box 2 from falling into the area between the two first mounting bases 210.

[0050] Reference Figure 1 The pallet loading station is located at the end of the feeding mechanism 200 and in the direction of movement of the material box 2 on the loading platform 230.

[0051] Better, refer to Figure 1 and 4The middle frame 120 is also equipped with material box clamping mechanisms 140 on both sides of the material position on the pallet, which are used to clamp the material box 2 and prevent it from shifting its position. The material box clamping mechanism 140 includes a second cylinder 141 and a push plate 142 disposed on the piston rod of the second cylinder 141. The second cylinder 141 pushes the piston rod to extend and retract, so that the push plate 142 fits against the side wall of the material box 2, adjusts its position, and prevents it from shifting.

[0052] Reference Figure 1 and 5 The material box clamping mechanism 140 is also provided with a material box blocking assembly 150 on its side, which includes a blocking cylinder 151, a blocking member 152 on the piston rod of the blocking cylinder 151, and a sensing element 153. After the sensing element 153 senses the material box 2, the blocking cylinder 151 is activated, and the retracting piston rod places the blocking member 152 in front of the material box 2 in the forward direction, thereby preventing the material box 2 from continuing to move forward.

[0053] Reference Figure 1 and 7 A lowering mechanism 800 is also provided below the side of the material handling mechanism 700, used to lower the material box 2 filled with empty tray 1 from the middle frame 120 to the lower frame 130. The lowering mechanism 800 includes a lowering cylinder 810, which is mounted on the lower frame 130. The top of the piston rod of the lowering cylinder 810 is fixed to a second mounting plate 801. Two guide columns 820 are arranged parallel to each other on both sides of the lowering cylinder 810. The bottom and top ends of the guide columns 820 are fixedly mounted on the lower frame 130 and the middle frame 120, respectively. A pair of fixing members 821 are fixed on the two guide columns 820, and two pairs of sliding members 823 are slidably sleeved on them. The fixing members 821 are fixedly connected to the second mounting plate 801, and the two pairs of sliding members 823 are fixedly connected to a connecting column 824. The connecting column 824 and the second mounting plate are arranged perpendicular to the guide columns 820 and parallel to each other. Two connecting columns 824 are arranged parallel to each other vertically. A side plate 825 is fixedly installed at each end of the connecting column 824, with the two side plates 825 being relatively parallel and facing the discharge mechanism 900. Two lowering box mounting seats 826 are respectively installed on the opposite sides of the two side plates 825. The two lowering box mounting seats 826 are located on one side of the discharge mechanism 900. A material box conveying mechanism 830 is installed between the two lowering box mounting seats 826.

[0054] Preferably, the two lowering box mounting bases 826 are fixedly connected by a connecting plate 827, thereby ensuring their stability.

[0055] During operation, a material box 2 is placed on the material box conveying mechanism 830. The lowering cylinder 810 drives its piston to extend or retract, thereby pulling the sliding member 823 up and down along the guide column 821. This drives the connecting column 824 fixed to the sliding member 823, the side plates 825 fixed on both sides of the connecting column 824, the lowering mounting seat 826 installed on the side plate 825, and the material box conveying mechanism 830 installed between the two lowering mounting seats 826 to rise and fall, thereby transporting the material box 2 between the lower frame 130 and the middle frame 120.

[0056] The material box conveying mechanism 830 includes a second motor 831, a second driving wheel 832, a second driven wheel 833, a third belt 834, a second drive shaft 835, a second driven shaft 836, two pairs of second rollers 837, and a pair of second conveyor belts 838. The second motor 831 is mounted on a connecting plate 827, and the second driving wheel 832 is fixedly mounted on the motor shaft of the second motor 831. The second driven wheel 833 is fixedly mounted on the second drive shaft 835, and the third belt 834 is tensioned and wound around the second driving wheel 832 and the second driven wheel 833. The second drive shaft 835 and the second driven wheel 833 are perpendicular to the two lowering box mounting seats 826 and are respectively connected to the two ends of the two lowering box mounting seats 826. The two pairs of second rollers 837 are respectively fixedly disposed at the two ends of the second drive shaft 835 and the second driven shaft 836. The pair of second conveyor belts 838 are respectively tensioned and wound around the second rollers 837 on the same side of the second drive shaft 835 and the second driven shaft 836. The second motor 831 drives the second drive wheel 832 to rotate, thereby moving the third belt 834. The third belt 834 drives the second driven wheel 833 and the second drive shaft 835 fixedly connected to the second driven wheel 833 to rotate. The rotation of the second drive shaft 835 causes the second rollers 837 located at both ends of it to rotate, thereby driving the third belt 834 to move. The material box 2 is placed on the third belt 834, thereby transporting the material box 2 to the discharge mechanism 900.

[0057] Reference Figure 6The discharge mechanism 900 has the same structure as the feeding mechanism 200, including a third motor 910, a third driving wheel 911, a third driven wheel 912, a third belt 913, a third drive shaft 914, a third driven shaft 915, two pairs of third rollers 916, a pair of third conveyor belts 917, and two oppositely arranged discharge mounting seats 901. The middle parts of the two discharge mounting seats 901 are connected by two connecting columns 902. The third motor 910 is mounted on the connecting column 902, and the third driving wheel 911 is fixedly mounted on the motor shaft of the third motor 910. The third driven wheel 912 is fixedly mounted on the drive shaft 914, and the third belt 913 is tensioned and wound around the third driving wheel 911 and the third driven wheel 912. The third drive shaft 914 and the third driven shaft 915 are perpendicular to the two discharge mounting seats 901 and are respectively connected to the two ends of the two discharge mounting seats 901. Two pairs of third rollers 916 are fixedly mounted at both ends of the third drive shaft 914 and the third driven shaft 915, respectively. A third conveyor belt 917 is tensioned and wound around the third rollers 916 located on the same side of the third drive shaft 914 and the third driven shaft 915. A third motor 910 drives the third drive wheel 911 to rotate, thereby moving the third belt 913. The third belt 913 drives the third driven wheel 912 and the third drive shaft 914, which is fixedly connected to the third driven wheel 912, to rotate. The rotation of the third drive shaft 914 causes the third rollers 916 located at its two ends to rotate, thereby moving the third conveyor belt 917. The material box 2 is placed on the third conveyor belt 917, thus transporting the material box 2 to the discharge mechanism 900.

[0058] The two discharge mounting bases 901 are mounted on the lower frame 130 via several mounting parts 904.

[0059] The automatic feeding machine of this utility model includes the following working steps performed in sequence:

[0060] 1. At the start of operation, a material box loaded with a pallet is placed on the feeding mechanism on the middle frame and sent to the pallet loading station by the feeding mechanism; at the same time, an empty material box is placed on the discharge mechanism on the lower frame and sent to the material box conveying mechanism in the lowering mechanism. Then, the lowering mechanism raises the empty material box to the middle mechanism and places it below the picking mechanism.

[0061] 2. When the empty material box is full of pallets, all the pallets in the material box at the pallet loading station are removed, and the box becomes empty; the lowering mechanism is activated to transport the material box loaded with pallets to the lower frame, and then the material box conveying mechanism sends it to the unloading mechanism;

[0062] 3. The lowering mechanism rises below the material handling mechanism; the feeding mechanism starts, transporting the empty material box at the pallet loading station to the lowering mechanism;

[0063] 4. The box feeding mechanism delivers the empty pallet-loaded material boxes from the material box conveyor mechanism, completing the automatic feeding of the entire box of materials.

[0064] The above structure allows for tight coordination and quick execution of each process, thus improving work efficiency.

[0065] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
